Pictures may show optional items
Click on the picture for details

The Model M443 is available in 4 basic configurations, 2 Cryogenic and 2 mechanically cooled.

The M443 is a standard performance Cryogenic chamber with high temperature ramp rates.  A castered stand is optional.

The M443M and M443MM are mechanically cooled chambers that are available with a number of compressor options depending on your cooling rate requirements. A castered stand is standard.

Single Zone Shock Chambers

The M443S is a high performance single zone shock chamber that meet the requirements of MIL SPEC 202, Method 107 testing.  The chamber features a top mounted controller and very compact footprint. Supplied with hinged lift off door.  The M443S is an  L–N2 Cryogenic chamber.

Model C controller is standard  
Model C4 programmable controller is optional

§  Cooling Rate

Cryogenic rates are highly dependent upon coolant type
(L–N2 or L–C02), pressure, and quality.  For more information download or request a copy of our brochure on Cryogenic Cooling

Mechanical refrigeration (not available on all chambers) rates are dependant on refrigeration system chosen and other factors.
Note: Cryogenic boost can be added to mechanically refrigerated systems to speed transition temperatures

    Heating Rate

Temperatures shown are for typical heaters. 
Faster and slower rates available.
